Most people, businesses and services were located in the capital. Many of the effects were immediate or primary , eg injuries from falling buildings. Some secondary effects didn't happen until many months later, eg cholera outbreaks. The effects of this earthquake were particularly bad because of the following reasons:.
Haiti is a very poor country without the money and resources to redevelop. Because there were few earthquake-resistant buildings , the devastation was massive. Many buildings simply collapsed or were damaged beyond repair. Geological Survey suggests that landslides will be a significant hazard, barreling into structures, blocking roads, and limiting access for recovery crews. Aftershocks will continue to rattle the region, and scientists will be keeping close watch on the sequence of shakes.
After the earthquake, Hough was part of a team of scientists that traveled to Haiti to install seismometers. She returned in the subsequent years to help establish an earthquake monitoring network and, she says, is working now to figure out "what we can do to support this fledgling network and this community.

That, however, is likely an undercount by an order of magnitude, according to the US Geological Survey. Under Hispaniola, two faults crisscross, but Haiti's major quakes have all been traced to the the Enriquillo-Plantain Garden fault system, which travels right under Port-Au-Prince.
The earthquake and Saturday's disaster both happened along that fault, and both involved the same type of plate motion. So it's possible the former led to the latter, Rychert said: "Sometimes when strain is released on one section of a fault it can cause stress to build on other parts of the fault system.
Earle said the agency is most worried about another quake hitting closer to Port-Au-Prince. The epicenter of Saturday's quake was just south of Petit Troup de Nippes, 78 miles west of the capital. But predicting that future quake is nearly impossible, Earle added. And regardless of whether another quake comes, aftershocks from Saturday's are expected to continue over "the next week, month, and beyond," the USGS said.
Big quakes struck in , , and , after which the region settled into a year-long quiet period. Then the big earthquake shattered that peace. A USGS study suggested the disaster marked "the beginning of a new cycle of large earthquakes on the Enriquillo fault system after years of seismic quiescence.
The report predicted, accurately, that Haiti and the Dominican Republic should prepare for future devastating earthquakes. Periods peppered with quakes on a fault line are normal, according to Earle, and there's little rhyme or reason to their timing, as far as seismologists can understand. Sometimes there are less or more pops at once. For you.
